At roughly the same time, Hoerling sent an amplification on his arguments and Miller sent a critique of Hoerling’s initial post. You can read both below. Keep in mind that neither writer has seen the other’s piece. (I asked Hansen for his thoughts on the complaints of Hoerling and Kerry Emanuel, another climate scientist who weighed in on Dot Earth. His response is at the end of this post.)

I have several papers well along in the publication process that make clear your characterizations are far off the mark. The editors prefer, indeed are insistent, that I not discuss these in blogs. Some scientists may be able to spend their time blogging and e-mailing without a significant impact on their scientific productivity — I’m not one of them — but I do make an effort to make my papers understandable to a wide audience.

About

By 2050 or so, the human population is expected to pass nine billion. Those billions will be seeking food, water and other resources on a planet where humans are already shaping climate and the web of life. Dot Earth was created by Andrew Revkin in October 2007 -- in part with support from a John Simon Guggenheim Fellowship -- to explore ways to balance human needs and the planet's limits.
